The new Custom Calling Services II (CCS II) have been provided by adding a 1A Voice Storage System (1A VSS) as a new node in the Stored Program Control network. Software and a new trunk circuit are required in the No. 1/1A ESS to provide call control, call filtering, and routing to a 1A VSS. The 1A VSS accepts the call and provides the package of voice services known as CCS II. The software required to provide these services is described.
